Abstract

The invention discloses a forehead wrinkle action detection method, comprising: extracting several video frames from a human face video to be tested; acquiring the forehead area of ​​each video frame extracted from the human face video to be tested; The detection operator calculates the gradient value of each pixel in the forehead region of each of the video frames extracted; calculates the variance of the gradient value of each pixel in the forehead region of each of the video frames extracted Obtaining the forehead wrinkle value of the corresponding video frame; judging the situation of the forehead wrinkle action of the human face video to be tested based on the forehead wrinkle value of each extracted video frame. Correspondingly, the invention also discloses a forehead wrinkle motion detection device. The invention has simple calculation and high efficiency.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to a forehead wrinkle motion detection method and device, and a living body recognition method and system. Background technique [0002] With the development of face recognition technology, more and more scenes need to use face detection to quickly identify a person's identity. However, criminals will use pictures or videos instead of real people for face recognition, so the security of the entire face recognition system cannot be guaranteed. The live face recognition can detect that the current face to be tested is a live face rather than a face in a photo or video, thereby ensuring the security of the face recognition system. When performing face recognition, it can help to identify whether the face is alive or not by detecting the forehead wrinkle action of the face to be tested. In order to realize the efficient and simple recognition of whether the human face is alive or not d...
